15kVA/150kV Power Frequency AC Withstand Test System

The 15kVA/150kV Power Frequency AC Withstand Test System is designed for dielectric withstand evaluation of medium- and high-voltage electrical equipment under power-frequency AC voltage. With a 150kV test voltage and 15kVA rated capacity, it provides a suitable high-voltage source for production inspection, laboratory testing, equipment acceptance, and commissioning applications.

The system consists of an Intelligent Electric Operation Console and an Oil Immersed Test Transformer. The motorized console enables smooth voltage adjustment and centralized operation, while the oil immersed transformer provides the required high-voltage output with reliable insulation and heat dissipation. Optional measurement, protection, and data recording functions can be configured according to project requirements.

• 150kV AC output for medium- and high-voltage insulation testing
• 15kVA capacity suitable for compatible electrical test objects
• Intelligent electric console simplifies voltage adjustment and operation
• Oil immersed transformer provides reliable insulation and heat dissipation
• Configurable over-voltage, over-current, flashover, emergency stop, and interlock protection
• Optional test data storage and USB export for testing records

• Power and distribution transformer insulation testing
• 10kV and 35kV switchgear withstand testing
• CT and PT dielectric withstand verification
• Insulator, bushing, and surge arrester testing
• Motor and generator stator insulation testing
• Short cable sections, cable joints, and terminations
• Electrical equipment commissioning and maintenance

Selection Note: The system is more suitable for relatively low-capacitance test objects. For long cables, large GIS, large generators, and other high-capacitance loads, a variable-frequency AC series resonant test system is generally recommended.
